How to Add Hydraulic Oil to Volvo Excavator and Check the Hydraulic Oil Level?

In daily maintenance, correctly adding hydraulic oil to the Volvo excavator and regularly checking the hydraulic oil level are the keys to the normal operation of the equipment. In this article, MyMROmarts will detail how to add hydraulic oil to a Volvo excavator and check the hydraulic oil level to help you keep the equipment working efficiently.

 

Hydraulic oil is the blood of the hydraulic system of the excavator. It is important in transmitting power, lubricating systems, cooling, and rust prevention. The quality and level of hydraulic oil directly affect the excavator's working efficiency and service life. Therefore, it is necessary to check and add hydraulic oil correctly regularly.

 

How to Check Hydraulic Oil Level on Volvo Excavator?

1. Preparation

Before checking the hydraulic oil level, you need to park the excavator on stable ground and the hydraulic oil has cooled down. Generally, it is best to check it after the equipment is stopped and cooled down for at least 15 minutes.

 

2. Find the Hydraulic Oil Dipstick

Volvo excavators are usually equipped with a hydraulic oil dipstick. The location of the dipstick varies from model to model, but it is usually located next to or on top of the hydraulic oil tank. You can refer to the equipment operating manual to find the specific location of the dipstick.

 

3. Check the Oil Level

Pull out the dipstick and wipe it with a clean cloth, then reinsert it into the hydraulic oil tank, pull it out again, and observe the oil level scale on the dipstick. If the oil level is between "Full" and "Add" on the dipstick, the oil level is normal. If the oil level is below the "Add" scale, you need to add hydraulic oil.

 

How to Add Hydraulic Fluid to Volvo Excavator?

1. Choose the Right Hydraulic Oil

Before adding hydraulic oil, first, make sure to choose hydraulic oil that matches the Volvo excavator. You can refer to the equipment operating manual to view the recommended hydraulic oil model. Using inappropriate hydraulic oil can cause hydraulic system failure and shorten the life of the equipment.

 

2. Prepare Tools

When adding hydraulic oil, you need to prepare a clean funnel and hydraulic oil. Make sure the funnel and hydraulic oil container are clean to prevent impurities from entering the hydraulic system.

 

3. Add Hydraulic Oil

Open the hydraulic oil tank cap

First, find the hydraulic oil tank and open the tank cap. During operation, be sure to keep the surrounding environment clean to prevent dust or impurities from entering the tank.

 

Use a Funnel to Add Hydraulic Oil

Insert the funnel into the tank port and slowly pour the hydraulic oil. During the addition process, pay attention to the hydraulic oil dipstick to confirm that the oil level gradually rises to the "Full" scale of the dipstick.

 

Recheck the oil level

After adding the hydraulic oil, reinsert the dipstick and check the oil level to ensure that the oil level reaches the "Full" scale. If the oil level is still insufficient, continue to add small amounts of hydraulic oil until the oil level reaches the standard.

 

4. Precautions

Avoid Over-Addition

Adding too much hydraulic oil can cause the tank to overflow and even damage the hydraulic system. Therefore, be sure to add the right amount of hydraulic oil and never exceed the "Full" scale.

 

Change the Hydraulic Oil Regularly

Hydraulic oil will deteriorate after a period of use. Regular replacement of hydraulic oil can effectively protect the hydraulic system.

 

Common Problems and Solutions for Volvo Excavators

1. Hydraulic Oil Consumption Is Too Fast

If you find that the hydraulic oil is consumed too quickly, there may be a leak in the hydraulic system. Check whether there is leakage in the hydraulic pipeline, joints, and cylinder seals. If a problem is found, the damaged parts or seals should be replaced in time.

 

2. Hydraulic Oil Deterioration

Hydraulic oil deterioration is usually manifested as oil discoloration, odor, or foam. This is caused by the hydraulic oil not being replaced for a long time or water entering the hydraulic system. The hydraulic oil should be replaced in time and the sealing of the hydraulic system should be checked to prevent water from entering.

 

3. Hydraulic System Noise Increases

The increase in hydraulic system noise may be caused by low hydraulic oil levels, hydraulic pump failure, or air intake inside the system. First, check whether the hydraulic oil level is normal. If the oil level is normal, you need to further check the hydraulic pump and pipeline to troubleshoot the problem.

 

With the above steps, you can easily add hydraulic oil to Volvo excavators and check the hydraulic oil level. Regular maintenance is the key to ensuring efficient operation of excavators.
